Blocking creature loses creature permanent type
I can't find an example that makes this possible but I'm sure some combo exists that could do it. (To be fair, I didn't look very hard because I don't have a lot of time)
If a creature is declared blocking another creature, and an ability or effect is applied at instant speed to cause the blocking creature to lose the permanent type Creature (example: if [[Vraska, Betrayal's Sting]]'s minus 2 ability could be activated at instant speed), what happens?
Does the now not-a-creature still take damage? While damage can't really destroy something that isn't a creature, would deathtouch still take effect? How would this interact with an attacking creature with trample?
